How PLECOTECH works
how it works

Not a mask. A mechanism.

PLECOTECH™ lifts the chlorine and copper off your hair and skin, then lays down a protective layer so they can't bond again. No green, no dryness, no smell. It's powered by our core ingredient, 100% natural red algae, with Dead Sea minerals and selected premium botanical extracts.

our story

“As athletes, we couldn't find anything that met our needs, so we decided to do it ourselves.”

TRIHARD started with swimmers and triathletes fighting the same losing battle: chlorine bonding to skin and hair, leaving dryness, itch and an odor that never washes out. So we built real protection for it, engineered around PLECOTECH™ and sustainably farmed red algae. Read more →
